摘要
通过对传统的GM( 1 ,1 )模型进行分析 ,指出了GM( 1 ,1 )模型实质是指数预测模型。提出了一种新的参数估算法 (最小二乘法 ) ,用这种新方法估算GM( 1 ,1 )的参数 ,并通过一个实际例子进行了分析。
Based on analyzing the traditional GM(1,1) model the GM(1,1) model the GM(1,1)model has been confirmed a exponential forecasting model can a new method of parameter estimation——least square method is put forward.The GM(1,1) model parameters are estimated by using the new method and with the analysis of a practical example.
